Sheriff Joe Lombardo said officers found “in excess of 10” rifles in his room. “We have no investigative information or background associated with this individual that is derogatory,” the officer added.

According to US media, Paddock is reported to have lived in a retirement village in Mesquite, Nevada, since June 2016 and is believed to have been born on April 9, 1953.

Records show he previously lived in Reno, Nevada, from 2011 to 2016, and also had an address in Melbourne, Florida, from 2013 to 2015.

He has also lived in Henderson, Nevada, and several locations in California since 1990, it is reported.

Mesquite is located about 80 miles, or an hour and 16 minutes, away from Las Vegas, along Nevada’s border with Arizona.

My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you!

Officers believe he had been in the hotel since 28 September. Police are also looking for two vehicles associated with the shooter, a Hyundai Tucson Nevada/114B40 and a Chrysler Pacifica Nevada/79D401.

There was an appeal to find another “person of interest” named Marilou Danley, 62, who officials say was travelling with the gunman before the shooting.
